Raoultella terrigena strain NCTC9997

Raoultella terrigena strain NCTC9997 is a Gram-negative, rod-shaped bacterium that is categorized as a facultative anaerobe, indicating its ability to thrive in both the presence and absence of oxygen. This strain possesses true flagella, which contributes to its motility in various environments. The habitat of R. terrigena includes fresh water, milk, plants, and soil, illustrating its versatility and adaptability to diverse ecological niches. It has been documented to infect hosts such as Homo sapiens and Nematoda. In humans, R. terrigena is recognized as an opportunistic pathogen, associated with several health complications, including urinary tract infections, sepsis, and subdural abscesses. The strain is characterized by having a single replicon, which is indicative of its genetic structure. Its accession number is NZ_LR134251.1, which can be used for further research and identification in genomic databases. From an ecological perspective, the presence of R. terrigena in fresh water and soil suggests its potential role in nutrient cycling and interactions within microbial communities. As an opportunistic pathogen in humans, it highlights the importance of monitoring environmental bacteria that may transition to pathogenic forms under certain conditions, particularly in vulnerable populations. Understanding the ecology and pathogenicity of R. terrigena is essential for public health and environmental microbiology.
